Every few hours my Security & Privacy settings window opens

    Configuration profiles found - This computer may have configuration profiles installed. These are sometimes used by malware.

Are you aware of any reason why you may have configuration profiles installed?

These are not usually present in personal machines.

Open System Preferences. Check if there is a "Profiles" pane (again, usually there isn't one, but there probably is in your machine). What do you see in there? Anything you recognized? Post a screenshot if possible.

To add to good Advise by @Luis S

Any Third Party Applications that will interfere with the normal operation of the OS,  is an invitation for disaster and comprising the Operating System

Any of the below should be removed as per Developers Instructions 

This will include BitDefender , Please read some of the may posting on this Application and arrive at your own conclusions

There are no known Windows-like Viruses in the wild that self replicate and affect macOS, because of the underling UNIX  Foundation and Permission Limitation. 

Additionally, and specific to Big Sur macOS 11 and Monterey macOS 12, the Operating System resides in a Sealed and Read Only Volume that can not be opened by the User or “ Bad Actor “ Software.

The Only thing this Antivirus software is protecting is the Bank Account of the Developers and for zero return to the User aside from the problems this software creates.

The The Built in Security  is all that is required to protect the computer.

There is Adware & Malware which will affect the computer and is generally downloaded from “ Shady “ Websites or Developers who Inject this software into the download.

Should “ Certain & Specific Software “ referenced from above be installed - it will negatively impact macOS. It is suggested, to download directly from a respected ASC Contributor, the application Malwarebytes for Mac. 

It is free or paid for added features. 

Run the Application and it should remove the malware / adware. Once done, restart computer and test.

Unsigned Files:

    Launchd: /Library/LaunchDaemons/com.epsecurity.bdconnectorservice.plist

        Executable: /Library/Bitdefender/bdconnectorservice

This may or may not have to do with the issue at hand, but you should not install bitdefender or any other third party "antivirus". They cause problems and offer no protection.

Read this excellent post about keeping your mac secure:

Effective defenses against malware and other threats

There could be some Launch Agent that does this.

Please run Etrecheck and post its full report here. Use the "additional text" button and paste the report into the text box.

I see. This being a managed computer, you should probably talk to the IT department that manages it.

I can understand why there are profiles, then. But using stuff like bitdefender is detrimental. Having the IT guys realize it, though, is a tall order...

Very much agree on all point by Luis S.

The IT Department may insist on BitDefender but may time to Up-Teach the Old Dog ( IT Depart ) just how macOS works - that is a very Tall Order
